N2 - Thermal monitoring of the long-track transmitter (Tx) magnetic mechanism of an industrial dynamic wireless power transfer (DWPT) system is necessary for its reliable operation. This article proposes an optical fiber composite winding (OFCW) for in situ thermal monitoring of the long-track Tx mechanism. Multichannel optical fibers are compounded on the Tx winding wire, which forms a composite structure, to detect the internal thermal distribution of the whole long-track Tx with fast response and high spatial resolution. A simplified optimization method based on magnetic and temperature field distribution characteristics is then studied to obtain a specific OFCW layout for rapid hotspot measurement and application extensions. Finally, an OFCW-based scaled-down DWPT prototype is established, and the experimental results with accurate thermal monitoring under different operating states confirm the feasibility and effectiveness of the OFCW. © 1963-2012 IEEE.
